Raspberry plant named ‘PS-08.019-25’

ABSTRACT

This invention relates to a new and distinct everbearing variety of raspberry plant named ‘PS-08.019-25’. The new variety is primarily adapted to the growing conditions of the central coast of California and is characterized by the following: mid-season primocane production with medium sized fruit of light-red coloration. Fruit is of consistent conic shape, releases very easily from receptacle and is of fair flavor. Foliage is slightly concave to strongly convex, medium green; possessing strong rugosity and always 3 foliate. Primocanes have an absent or very weak waxy coat, green spines, and sparse thorn density and have absent to very weak anthocyanin coloration.

Latin name of the genus and species of the plant claimed: Rubus idaeus.

Variety denomination: ‘PS-08.019-25’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct fall bearingraspberry variety designated as ‘PS-08.019-25’. This new variety is aresult of a controlled cross made in 2008 in Watsonville, Calif. betweenraspberry variety ‘PS-1764’ (patented, U.S. Plant Pat. No. 15,439) asthe female parent and raspberry variety ‘04.3890’ (unpatented) as themale parent in an ongoing breeding program. The variety is botanicallyknown as Rubus idaeus.

The seedling resulting from the aforementioned cross was asexuallypropagated by dormant canes in Santa Cruz County, Calif. and wassubsequently selected by the inventor from a controlled breeding plot inWatsonville, Calif. in 2010. After its selection, the new variety wasfurther asexually propagated by dormant canes, roots and non-dormantroot shoot cuttings in Santa Cruz County, Calif., San Joaquin County,Calif. and Siskiyou County, Calif. The new variety was then extensivelytested over the next several years in fruiting fields in Santa CruzCounty, Calif. This propagation has demonstrated that the combination oftraits disclosed herein as characterizing the new variety are fixed andremain true to type through successive generations of asexualreproduction.

BRIEF SUMMARY OF THE INVENTION

‘PS-08.019-25’ is primarily adapted to the climate and growingconditions of the central coast of California. This region provides thenecessary year-round temperatures required for it to produce andmaintain a strong vigorous plant and to remain in fruit production fromJuly through December on primocanes and in the ensuing year from Maythrough July on floricanes. The following traits have been repeatedlyobserved and are determined to be unique characteristics of‘PS-08.019-25’, which in combination distinguish this raspberry plant asa new and distinct variety:

-   -   1. Green spines    -   2. High fruit yield    -   3. Light to medium red fruit color    -   4. Absent to very weak primocane glaucosity    -   5. Fair flavor

The raspberry variety that is believed to be most closely related to thenew raspberry variety ‘PS-08.019-25’ is the raspberry variety ‘GRANDEUR’(patented, U.S. Plant Pat. No. 20,459). In comparison to the similarraspberry variety ‘GRANDEUR’, ‘PS-08.019-25’ differs by the followingcombination of characteristics described in Table 1:

‘PS-08.019-25’ differs from its parents, ‘PS-1764’ and ‘04.3890’, by thefollowing combination of characteristics described in Table 2:

For identification, a series of molecular markers have been determinedfor this new variety.

DETAILED BOTANICAL DESCRIPTION

‘PS-08.019-25’ has not been observed under all possible environmentalconditions. The characteristics of the new variety may vary in detail,depending upon variations in environmental factors, including weather(temperature, humidity and light intensity), day length, soil type, andlocation.

The aforementioned photographs, together with the following descriptionof the new raspberry variety ‘PS-08.019-25’, unless otherwise noted, arebased upon observations taken during the 2016-2017 growing season inWatsonville, Calif. Primocane measurements and ratings were taken fromplants of ‘PS-08.019-25’ dug from a nursery located in Siskiyou County,Calif. during the middle of October 2015 and planted approximately 3 to4 weeks later in Watsonville, Calif. The approximate age of the observedprimocane plants is 7 to 8 months. Floricane measurements and ratingswere taken from the same planting of ‘PS-08.019-25’ at an approximateage of 16 to 18 months. Yield observations and fruit qualitycharacteristics are averaged from three years of data collected from the2013 through 2016 production seasons. Flower measurements andcharacteristics are from secondary flowers unless otherwise noted. Fruitcharacteristics and measurements are from secondary fruit unlessotherwise noted. Foliage characteristics and measurements are from3-foliate foliage unless otherwise noted.

Color terminology where noted follows The R.H.S. Colour Chart FifthEdition, Royal Horticultural Society, London, United Kingdom (1966).

The following Tables 3-7 describe fruit, plant, foliage, flower andpest/disease characteristics of the new raspberry ‘PS-08.019-25’ incomparison to the similar raspberry variety ‘GRANDEUR’ (patented, U.S.Plant Pat. No. 20,459).
